This module is the functionally similar to libc.so.6 on Linux.

Heap
The latest version of dlmalloc is included in SceLibKernel. Most of the assert checks and security are included.
Thread specific data
Each thread owns a private 2048bytes memory region with specific data. The end of this region is pointed by the TPIDRURO register (thus, the start of it is TPIDRURO - 0x800).
